it is exactly what i was looking for
I looked everywhere for a mini alternator that would fit into the tight engine compartment of my 1928 Plymouth coupe that has a 500 cu.in big block amd have enough amperage to run all the electrical at low rpm when crusing around town at night. This unit is perfact.

This mini alternator is a great idea but it cost over $100 expedited freight to find out they don't actually work.

Bought this for my new bracket race build. Wanted a smaller alternator but didn't want to spend the big prices for the other brands. Definitely a win here.
